   You may also find it easier to find parts in 0805, depending on the part.

   There are other methods, as I mentioned in my first reply (right about   
   as you were writing this, I'd guess, so you wouldn't have seen them) -   
   the camera-scope and screen is probably the most affordable of them,   
   unless you find a handy source for cheap used microscopes and find a   
   suitable one among those, or happen to have one. Trick being you need a   
   scope that gives you room to work - dissection scopes are often as   
   suitable (optically) as those sold as "assembly scopes."   
      
   Yes, cutting islands in copperclad is a very handy 1-off at-home   
   technique with SMT. For some applications (not all, particularly high   
   frequency ones) generic adapter boards to get back to DIP pin spacing   
   are also handy/useful.
